Abstract
Combined Vivaldi notch and meander line loaded antennas are concatenated in an array to provide an ultra wideband antenna having a decreased low frequency cut-off due to the concatenation. In the concatenation process, plates of adjacent antennas are shared so that one plate is used for both of the adjacent antennas. In a preferred embodiment, the side plates and the top and bottom plates are identically configured.
